What to Do When a Mercedes-Benz C200 Fails to Start After Power Loss?

If the battery has been disconnected or is low on power, pull the switch upward until the side window is completely closed, and hold the switch in this position for 1 second. Hold the switch in the closing direction until the roller blind is fully closed, then continue holding the switch for another 1 second, and then hold the switch in the opening direction. Hold the switch in the opening direction again until the sunroof opens another 10 centimeters, then release the switch and hold it in the closing direction.
I had just bought a Mercedes-Benz C200 when I ran into the annoying problem of the car not starting after a power outage. That day, there was a heavy rainstorm causing a power failure and restoration. When I went to drive, pressing the button gave no response at all, making me jump with anxiety. Later, after some research, I found out it might be due to the battery being completely drained or the electronic anti-theft system being locked. I first tried using a power bank connected to the cigarette lighter port to charge it for a while, but it didn’t help much. Then, I unplugged and replugged the key a few times to reset the anti-theft system, but it still didn’t work. A friend suggested calling a nearby repair shop or Mercedes-Benz 4S店 for towing service. They brought professional tools for testing and discovered that the battery was too old to hold a charge. Now, I regularly check the battery’s health and have even installed a voltage stabilizer at home to prevent power outages from affecting the car. This experience reminded me that even new cars need attention to electrical maintenance.
I've been driving a Mercedes-Benz for over a decade and have experienced several no-start situations after power loss. The C200, being a premium model, is particularly sensitive. The main causes are usually battery issues, where discharge accelerates after power loss, or when the anti-theft control module detects anomalies and automatically locks the vehicle. My approach is to first calmly check: whether the ignition key is properly inserted and if the dashboard lights are on. If there's no response, I use simple tools to test the battery voltage. If it's too low, I call for a jump start. If it still doesn't start, I check if any fuses are blown. During regular maintenance, I ask the mechanic to thoroughly test the electrical system, and adding a voltage protector can reduce risks. Remember not to force the car key or repeatedly attempt to start the engine, as this can easily damage electrical components.
When the Mercedes C200 fails to start due to power loss, first check if the battery is depleted. Try jump-starting it by connecting jumper cables to another vehicle. If it still doesn't start, inspect the anti-theft system status and attempt resetting the key or system. If necessary, contact professional maintenance. Always prioritize safety and avoid risky operations.
